Panels are sandwich double skin type with outer sheet as Pre painted galvanized steel and inner as galvanized sheet.
Polyurethane form insulation is injucted between the two sheets to make sandwhich panels. A minimum density of 40kg/m3 is
maintained however higher density up to 48kg/m3 can also be achieved. Stainless steel 304, Stainless steel 316 or Aluminium sheets can be provided for double skin panels as an option. The Polyurethane injected panels have an excellent heat insulation and noise reduction properties and add extra mechanical strength and rigidity to the structure. The factory injected PUF is CFC & HFC free and self extinguishing type. The maximum heat transfer coeffi cient for 25 mm, 50 mm and 50 mm thermal break is U = 0.73 w/m3K an 0.35w/m3K respectively. Panel are fi xed to profi le with high quality gasket which has excellent sealing properties and good resistance to compression stress and temperature.
